After struggling to get Win7 installed on a z820 workstation to no avail I came across an HP article regarding UEFI installation and figured I give it a shot since I wasn't able to get anything else working (I am able to get a USB version of Windows Installer running but it cannot see the disks, regardless of their format, the ACHI or IDE settings, the RAID settings etc) So I followed the guide up until the point where it said change the "Option ROM" to EFI, there was no Option ROM in my BIOS setting (BIOS 2.07), there were a number of others, which I changed one at a time to "EFI" until I ran into my current issue. The screen stays black on boot and then the blue led lit power button changes to red about a minute into booting. HELP!

When the power button LED turns red, it flashes a "blink code". How many flashes does it do in a row? The pattern will repeat after a short pause.
